For the past several years, a group of friends has gathered every week in the living room of a suburban home in Logan, Utah, to sing long-forgotten songs. It's a fun way to spend the evening, but it's also therapy for a dear friend.

"I used to know 800 songs," Toelken says. "I had this stroke, and I had none of these songs left in my head. None of them were left."
In Tuesday's primary, many of those showing up to vote will not be registered as Republicans. In New Hampshire, voters unaffiliated with either party can vote in the primary.
